Golf/GTI VI :: Whoosh Noise When Turbo Spin Up In 2nd And 3rd Gear?
I noticed that the turbo sounds kind of weird when it first spins up in 2nd and 3rd gear. Kind of a rattly whoosh noise before the normal whistle. Is it normal? I thought it was the "noise maker" thing, but FWIW the 2011's don't have it.
View 4 RepliesPassat (B5) :: Turbo Sounded Pretty Loud And Made Whoosh When Throttle Released
Ok first of all i know this sounds really stupid. I got curious of the intake system and I unbolted the tube that does down to the (turbo i think) anyways I figured it was the intake for the engine. Anyways I went for a quick little drive, and it was not the intake for the engine it was the for the turbo. The turbo sounded pretty loud and made a whoosh when the throttle was released. Cool. 2 min later the car shut off i started it back up drove home, and put every back the way it was suppose to be! and there is a check engine light. My question is... How do I reset the light myself instead of the dealer doing it, I thought i remembered how to do it somehow without anything. Btw was doing that anyway harmful?
View 4 RepliesGolf/GTI VI :: Boost Leak Between Exhaust Manifold And Turbo
I have a leak between the turbo and the exhaust manifold. The golden clamp (c-clamp? v-clamp?) broke, and now there is a gap between the two. The dealership doesnt cover it under powertrain warranty (my car has passed regular warranty) but worst of all they do not sell the clamp on its own.
I posted a link to a picture below, it isn't my turbo.

Golf/GTI VI :: Blown Turbo / Slight Boost Leak
Recenly, i feel like i haven't been hitting boost, so i went to get an oil change last week. I did the oil change, and everything seemed ok, I thought it might have been a slight boost leak. This morning i check my drive way to see a little oil on it. So i check the dip stick and the oil level is already at a minimum. Do you think i have a blown turbo due to the oil drop and lack of boost. It hasn't been a 100 mi since the oil change either.
View 7 RepliesLexus GX 2010+ :: Loud Whoosh Noise When Engine Turned Off
Odd, relatively loud "whoosh" noise when they turn off the engine? It sounds pneumatic in nature, like a pump or servo of some sort sealing or depressurizing? I should note that I park in a garage, which may amplify it. Definitely more noticeable if you open the driver door or window then kill the ignition.
Second, I don't know if it's the cold, a bad batch of gas, or just normal but the motor seems to make a clack clack clack noise when stopped/at idle. It's not consistent and doesn't seem to affect drivability. I just hope it's not knock or slap, i.e., indicative of serious issues. Am I just being paranoid and overly sensitive?
Golf VI R :: Loud Hissing Noise From Passenger Side / Boost Won't Go Over 24lbs
So for the last 2 days I heard this loud hissing noise from the passenger side of the car and also noticed that my boost won't go over 24lbs. So I called my local tuner shop Innovative motor sport in Stratford and was told to bring it down to check it out. Less then an hr later I was at the shop and we where putting it up on the ramps to get under to take a look. I took out the panel covering under the motor and looked up to find a hole in my turbo outlet coupler. Tom at IMS had an extra laying around and let me use it till I get a replacement.
View 10 RepliesElantra MD (2010-15) :: Turbo / Quick Whoosh Sound When Started
I am a proud owner of a 2012 Elantra GLS(auto 1.8) and i like to use the sport mode "Shiftronic" all the time. When I started using it, i noticed a nice quick woosh sound almost like a mini turbo, only when i shift at 5500 to 6000 rpm. it sounds like air pressure releasing when i shift at high rpms.
obviously, i do not have a turbocharged engine, but its a pretty loud sound, people can hear it outside of my car if within 15 feet. I have noticed this for the past year and a half but never found out what it was. I will say that I have added a short ram intake into the car, but I have heard this sound way before I put the intake in. There was no change of sound when I added the intake, so it is not intake related. And I know what intake sound is. note it only happens when shifting at high rpms, with my foot still on the gas pedal. it gets louder with higher rpms. it sounds like compressed air being released. Like air is building with rpm, then releasing at shifts. Im not mechanically inclined but I believe that is what it is.
What exactly is causing the sound(what parts) and if it could be stressing my car if done too often?
Passat (B5) :: Loud Spooling - Boost Leak?
I am noticing that my spooling is getting louder and louder and I am suspecting a boost leak! I a m wondering if i do have one is it causing any damage? my guess would be running rich but id like to get another opinion! my boost used to peak at 11 and now since the noise is getting louder its only peaking at 9! im gonna do a boost leak test but in the mean time im not gonna drive it if its bad!
View 4 RepliesGolf VI R :: No Turbo Boost - Weird Sound When Hit The Gas
I have a 2012 R with 85,000 miles, APR chip running 93 octane with a HPFP and VWR cold air intake. I was driving my car today (slow driving on highest) and all of a sudden I felt no turbo boost, and heard a weird sound whenever I hit the gas. Car moved but would not get above 3500 rpms and couldn't really get past 60 mph. Again, absolutely no boost (I have a boost gauge as well to verify).
About to drop off the car at a shop but had a couple questions:
1. If the turbo is blown, can I still drive the car to the shop (not too far) without damaging the engine itself?
2. if the turbos needs to be replaced, what are my options besides getting the stock turbo replaced, without getting some crazy setup? This is my daily driver and I don't want to spend money beyond what I need to get it fixed, but it there is a stronger more reliable turbo for about the same as a OEM, I would want to consider... Also price for OEM replacement??
3. Without the mechanic looking at it, I'm just assuming it's the turbo but what else could be the issue? All the lines looks intact and intake is fitted correctly. I did have issues with my cam follower getting damaged at 45,000 miles (there was a hole in it) and I have been replacing it every 20,000 miles since. Didn't have any issues for 40,000 additional miles, but could damage to that cause turbo failure?
Golf IV R32 :: Turbo - Misfire Under Boost / 1k RPM Idle (high)
Car started to do some weird stuff today. Misfiring under high load, as I get into boost.
Idle is around 1000-1100 RPMs. Cold start is fine, idle is normal in terms of going higher a bit, but then it sits at 1kish. This started last night after the car sat for a couple hours. Totally normal running and driving prior to this.
I've seen all the MKV threads about it that suggest everything from battery, to alternator, to grounds, to vacuum leaks, to intake leaks, to MAF.
Golf IV / Jetta IV :: Turbo Flutter Over 20 Pounds Of Boost
I have an 03 GTI 1.8t with the stock K03s turbo and i used to boost to 25 pounds. Had to put a new motor in and now i when i boost above 20 pounds i get turbo flutter and loose boost. I can boost anywhere up to 20 pounds and the turbo doesn't flutter at all.
I had a spring on my waste gate which i have taken off and it changed nothing. I tried a different diverter valve and it didn't change anything. I unplugged the MAF to see if the N75 or the there was a boost leak and extra air wasn't being monitored but still changed nothing. It has nothing to do with my RPM range just when i boost over 20 pounds. I am planning on doing a leak down test to make sure there isnt a boost leak....
GTI 337/20th Anniversary :: Boost Leak - Loud Whooshing / Hissing Of Air
02 GTI 1.8T ... Stage 2
Was running the car at about 4500 rpms in 5th gear. All of a sudden lost power and heard a loud whooshing/ hissing of air which sounded like it was coming from under the front passenger side of the car. Lost about 50% of power in all gears. What I screwed up and broke?
Ford 6.7L Power Stroke Diesel :: 2013 - Turbo Noise - Loosing Boost Over And Over Again
I have a 2013 F350. Since it was new in August the turbo has made a chattering sound that sounds to me like the waste gate (if it had one) is opening and closing rapidly. Almost like its building boost and dumping it over and over again. Usually happens when it is in 6th gear around 1700 rpm under light load. It also does it from time to time while plowing snow. You can power through it or let off and it will go away. My local dealer where it was bought new put a new turbo on it and the problem still persists. The truck just turned over 8k miles and has been in several times in attempt to resolve the issue. They say that there are no codes on the truck nor does Ford have anything on their service web. My dealer claims that no one has ever had the issue.

I recently installed a k04 turbo, when I try and accelerate hard my wastegate just seems to open up very quickly without building much boost. I don't have a boost gauge or anything like that installed. Do I start by adjusting the wastegate actuator, or install MBC. Pretty new to this still.
View 12 RepliesGolf IV / Jetta IV :: High Pitched Noise / Whoosh Sound From Intake At Low Rpm When Car Is Cold
I have a 2002 jetta 1.8t with unitronic stage 2 ECU and following mods:
ssqv BOV with recirc fitting (so acts like a DV)
3 inch open downpipe
Water/Meth injacetion (-35c washer fluid)
Short ram intake+heat sheild.
Spring loaded wastegate.
So for a while now I could hear a very quiet high pitched sound along with a whoosh sound from the intake at low rpm when the car is cold, after 5-10 minutes of driving the sound changes to where i just hear the wooosh from the intake, no high pitched.
I went out, let my car park for about an hour or 2 in 0c temp. went to drive it,everything is fine, the car just hit 90c. so i floored it, but traction control was on and i have winter tires, so it barley got to 4k rpm. CEL started flashing, no throttle control, really annoying high pitched sound from engine bay with lightest touch of throttle. the trubo was boosting to 22 psi and holding up to 16 PSI at redline before this happened.
The car would struggle to stay at idle, massive vibrations. but after reeving to 2k+ rpm no issue staying at that rpm, no blue/black smoke from exhaust. i scanned it and only got misfire codes and this strange code : "17925 - power supply relay for ecu (J271 or J363): electrical malfunction"
I had to clear the codes 3-4 times and restart the car 3 times for the power supply relay code to go away. but all the misfires, the high pitched sound stayed. it would misfire while driving, then stop, and then again.
I also logged with VCDS, and flooring it from 2k rpm to 2.6k rpm resulted in 0 extra boost over idle (idle boost was 980mbar).
Is my turbo blown 100% because of that sound, or could it be something else causing the "dentist drill" sound? And what about the power relay issue for ECU, could this cause any of the symptoms?
Golf/GTI VI :: Loud Hissing Noise - Exhaust Leak?
I feel as though my APR turboback has an exhaust leak.
There is a loud hissing noise that overwhelms the exhaust, turbo and engine noise. What it is. Sounds like a loud hissing when then turbo begins to kick it. Not normal, and it slowly has gotten worse and more noticeable.
I have a feeling its the downpipe, but I can't check it myself. When i give it gas and the hood is open (at a standstill obviously), the engine compartment smells like exhaust fumes.
Could be playing mind games with myself. What do you all think? Any way to surely test and see? I am taking it to dealership on Tuesday to double check.
Phaeton :: Air Suspension Making Short Loud Whoosh Sound
I have been noticing that after a trip my phaeton's suspension makes a short loud whoosh sound after i lock it , it usually makes a quiet sound like "sssssssssssss" which lasts about 3 seconds and lowers the suspension , but sometimes , about once 3-4 monts or so makes this loud woosh and lowers rapidly . Is it normal that sometimes the car should release the pressure that fast?
View 1 RepliesGTI 337/20th Anniversary :: Extra Loud Whoosh Sound When Stepped On Gas - Random Misfires
So I was driving home from my girls house the other day, i stepped on the gas pretty decently, and instead of the normal "whoosh" from the intake, i hear the "whoosh" with an extra loud "whoosh" sound. Then when i came to a halt, the engine wanted to stall out and was sputtering incredibly bad. car seems to run fine @ 2k rpms+. Now it actually does crap out on me, so I am currently not even driving it.
I got fault codes p0300, 0301, 0303, 0304. random misfires in cyls 1,3,4 right? I checked my hoses and I don't seem to have a leak anywhere...
Golf IV / Jetta IV :: Loud Screech While In Full Boost
I just replaced my my k03s with another one with only 20k on it. After I did this, I noticed a loud screech sound when in WOT. The screech lasts a little bit after i left off the gas when revving in neutral. I've been doing research on here, and I've read that it could be a boost leak somewhere or even the turbo dying. The shaft play is minimal though.
